Not sure what you mean by "pure" versus "custom"? Any RP2040 variant that is listed in the definitive guide will work, and many others will also work, but haven't been tested extensively enough to say they are all "supported".Hi all, sorry for the stupid question.
I would like to install a picofly on the Mariko I would like to know: is a pure RP2040 better or a custom rp2040?
To be clear, they cost a little more and have the flat cables included, I think the installation is also slightly easier.
Thanks
